One space is public and one is private. One space is optional/avoidable and one isn't. How could this be easier to understand?

When it specifically says it’s a public locker room how is it private? If other people can see you then is it really private?

The article never once says "public locker room", it merely says "locker room". These are, presumably, parts of private establishments such as pools, saunas, gyms, etc. That is, one has to make the conscious choice to enter such an establishment.

Even if it's a publicly-funded establishment such as, say, a municipal swimming pool, the conscious choice to enter into such a place versus walking through an open street aren't comparable.
